LOOM FOR WEAVING TUFTED PlLE FABRICS.

SPEUIFICATION forming part Of Letters Patent NO. 668,67 9, datedFebruary 26, 1901.

Application filed February 17, 1900. Serial No. 5,596- (No model.)

To all whom it may concern.-

Be it known that I, J AMES IRVEN COLLINS, of the city of Amsterdam,county of Montgomery, and State of New York, have invented a new anduseful Improvement in Looms for Weaving Tufted Pile Fabrics, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to improvements in looms for weaving tufted pilefabrics of the moquette carpet variety; and its purpose is to enable theproduction of such fabrics having widths which cannot be woven uponlooms of this class as ordinarily constructed. As is well known in thisart, the width of the fabric is limited to the length of the tuft-yarnbeam and its carrying-frame. This frame and its beam are necessarily ofvery light construction, and when the length of the frame is extendedbeyond a definite limit it has been found that the frame, together withits beam, developed a tendency to sag, and thus cause an uneven feedingof the tuftyarns carried by the beam.

By my invention the objection hereinbefore noted is obviated, and as ameans to attain this end I employ a suitable mechanism which serves tosupport the tuft-yarn carrying frame at a point or points intermediateits ends while the frame is being transferred from the spool-chains tothe place where the tufts are incorporated into the fabric.

A practical embodiment of my invention is represented in the drawingsherewith, in which Figure 1 is a View at the right, showing parts of aloom, together with my invention applied thereto. Fig. 2 is a view inelevation of one of the tuft-yarn-spool frames employed in my invention.

A designates the main frame of the loom; A, one of the sprocket-wheelsaround which pass the chains for carrying'the series of tuftyarn-spoolframes B employed in weaving this class of fabrics, and C is one of thetransferring-arms employed to effect a transfer of the tuft-yarn-spoolframes from the chains to the warps. D is the reed or comb employed forbeating up the tufts and the wefts of the fabric. These parts are oldand well known in the art.

The tuft-yarn-spool frame B may be of ordinary construction in so far asthe springbearings 17 at the ends of the frame and the tuft-yarn tubes bare concerned. In the construction illustrated, however, I have providedintermediate bearings b, so that the tuft-yarn-spool frame is adapted tosupport a plurality of tuft-yarn spools B. The opposing ends of thespools B are near to each other by reason of thin bearings b beingemployed, so that the frame carries what is practically one spool ofconsiderable length, the tuft-yarns carried by such spool being fedthrough the tubes 19 which latter are arranged on the spool-frame B inan unbroken line. As thus constructed the said spoolframe, with itsspools, if supported only at its ends, as is usual, would sag at themiddle to such an extent that an uneven feeding of the tuft-yarns wouldoccur, and consequently imperfect fabrics be produced.

In order to sustain the parts of the spoolframe in alinement, I haveprovided devices which support the spool-frame intermediate its ends atthe time the tuft-yarns are being incorporated into the fabric. Suchdevices embrace the arm E, having at its front end a finger or lipe,which is designed to be brought under the spool-frame and afford thesame a proper support at the necessary moment. This arm E has movementssynchronously with the transferring-arms O. The shaft Eis provided witha cam F, adapted to act upon a roll f, carried by a lever E, pivoted atG at the lower part of the loom. The upper end of this lever E ispivoted at g to the rear end of the arm E. By means of the devicesdescribed a suitable longitudinal movement is given to the arm E.Mounted also on the shaft F is a cam F which acts upon a roll f, carriedbya lever E the latter being also pivoted at the point G at the lowerside of the frame. The free end of the said lever E is connected at g tothe lower end of a link E the upper end of which is pivoted at g to thearm E at a point intermediate its ends, whereby the necessary verticalmovements are imparted to the arm E.

I have described a loom as provided with a single supporting-arm E,designed to sustain the tuft-yarn-spool frame at its center;

but it is to be understood that my invention is not to be limited to aspool-frame thus supported, for obviously such spool-frame might besupported at more than one point in its 5 length if found necessary ordesirable.

WhatI claim as my invention, and desire to secure by Letters Patent, is

In a loom for weaving tufted pile fabrics, the combination of atuft-yarn-spool frame 10 carrying a plurality of tuft-yarn spoolsarranged end to end, with arms to efiect transfer of such spool-frame,and an arm to support such spool-frame at a point intermediate itslength while being transferred, substantially as described.

In testimony whereof I have hereto signed my name in the presence of twosubscribing witnesses.
